9 Claims. (Cl. .51-187.).

l Myinventionrelates to a sandingand -.boiling tool andy has for its primary `objectithe provision of atholding tool to which.abrasiveystrips such as sandpaper, emery cloth, steel wool, etc. can be easily;andquickly applied and removed therefrom and also providing a tool to whichbuing or 4wax.- v

ing pads can be attached in much the same mannerffor use in hand polishing various kinds and typesof surfaces.

Another and further object of my invention is the provision of a tool Ato which abrasive strips `can readily be attached and detached and which enables the operator to easily andquickly use these strips for abrasive kpurposes with the contours of the tool being such thatentrance can be made into various types, and kinds of openings, f

grooves and the like so that thetool may. be.used

after being placed in proper position around the 1 base of the tool, sov that the tool can'always be quickly and easily used for either abrasive or polishing action as maybe desired.

Another and further object'of my invention is the provision of a tool in which various thick- Y nesses of abrasive materialA may be applied'thereto and such material can be held in properv relationship on the base of the tool yfor usev either-as an abrasive or a polishing material. Y For instance, the dimension ofthe tool is such that the ordinary rectangular sheet of sandpaper or-emery cloth can be folded in four or morelayers and placed in position on the tool "and as one surface becomes worn'the material can hel ree folded in such manner that the unused portion can be placed in position for use in abrading and this process repeated until'all the surfaces 4ofy the strips can be used. When this strip 'is folded the thickness'of the material is, of course, materially increased and the tool vis so constructedas to acccmmodate the holding of strips of materialv of varying thicknesses.

These and other objects of my invention will be more fully and better understood by reference to the accompanying sheet of drawings .and in which:

Figure 1 is a top elevational view of my` improved tool;

Figure 2 isa side elevational .View of.. the' tool shown vin Figure .1;

' `form Aas shown.,` The spring clip 25` has: .curved 3 but slightly canted as shown in Figure 3 when in closed position.

Transverse grooves 32 and 33 are provided adjacent the ends of the hand hold portion II, these recesses providing shoulder portions 34, 34 with jack levers 36 and 31 being provided, which are rectangular in cross-section and are seated in the grooves 32 and 33 respectively and have inner end portions 38 and 39 angularly disposed thereon which normally t into slots 40, 40 provided in the top of the hand hold portion I I when the jack levers are in horizontal position. The jack levers 36 and 31 have finger pieces 4I and 42 on the outer ends thereof which project to the side of the hand hold portion Il on opposite sides of the hand hold portion II with cut-outs 43 and 44 in the spring holding member 25 being provided to enable the operator to more easily engage the finger pieces 36 and 31 so as to manipulate the jack levers 36 and 31 and will be hereinafter described.

The jack levers 36 and 31 can be rotated only through an arc of 90 with the inside edges of the finger pieces 4I and 42 near the ends extending vunder the edge of the cover plate 25 particularly shown in Figure l, so that these ringer pieces cannot be rotated beyond substantially a horizontal position. The angular ends 38 and 39 of the jack levers 36 and 31 are normally fitted into the slots 40 and 4I formed in the hand hold portion II, so that when these jack levers are in their normal horizontal position they will not drop out of place in the hand hold, nor can they be removed therefrom.

The jack levers 36 and 31 are rectangular in cross-section and when turned to vertical position lift the cover 25 so that its ends are in open position as shown at the right side of Figure 3. When turned into horizontal position their long diameter is parallel with the top of the block as shown in the left side of Figure 3, and they exert no pressure on the spring member 25, which moves to closed position because of its resiliency as shown at the front end of the tool in Figure 3 of the drawings. A cushion 45 is placed over the face of the base portion I2 of the tool and a strip of abrasive 46 is shown, which is in position around the ends ofthe base portion I2 and clamped by the end 3| of the spring holding -member 25 at the forward end, but open at the rear end, as shown in Figure 3 of the drawings. The curved ends 22 and 23 of the hand hold por- .tion conform to the curved ends of the holding member 25.

From the foregoing description it is believed that the operation of this device can be easily and quickly understood. When it is desired to place a strip of abrading or polishing material on the base I2 of the tool one of the jack levers is turned to vertical position, as shown in Figure 3, which frees the end ofthe spring member 25 under which the particular jack lever is mounted from the top surface of the stepped portions I1 or I8 and the abrasive material 46 is placed around the end of the base portion With its end under the raised free end of the spring holding member 25. In rotating the jack levers 36 and 31 to vertical position, they are supported by the edges in the channels 32 and 33 and rest a'gainst the shoulders 34, 34 and at the same time the sides of the angularly turned end portions 38 and 39 of the jack levers 36 and 31 engage against the underside of the cover 25 thereby preventing the over rotation of the jack levers 36 and 31,

va spring clamping' member secured to the body open position so that whatever material may be used such as an abrasive or polishing material can be placed in position around the base I2 of the holding member. If this material is longer than ordinarily required, the ends are fitted into the recesses I1 or I9 at the end of the hand hold II and upon the material being fitted around the base at one end the jack lever at that particular end is released and the material is clamped in position on the base member I2. The material is then drawn tautly around the opposite end of the base member I2 and inserted under the open end of the spring member 25 and the jack lever turned so as to release the spring holding member 25 into clamping position so that the ends of this member are tted down over the ends of the abrasive 46 and the tool is ready for operation. Should it be necessary to replace or renew this material the reverse operation can be`performed, providing a tool in which abrasive material or polishing material can be easily and quickly substituted by the operator for various kinds and classes of work.

While I have described more or less precisely the details of construction, I do not Wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient Without departing from the spirit or scope of my invention.
